The north coast of Australia, both from its more interesting formation and the lack of settlement, has received a good deal of attention from our navigators of the present century, and by far the most fascinating part of Captain Flinders' log refers to the north coast.
In 1802, we find him following the track of M. D'Entrecasteaux round the Great Bight. Flinders seems to have been as much puzzled as he was regarding the great extent of level cliffs passed. He conjectures that within this bank, as he terms it, there could be nothing but sandy plains or water, and that, in all probability, it formed a barrier between an exterior and interior sea. He little thought how, some years afterwards, a lonely white man would tramp round those barren cliffs, eagerly scanning Flinders' chart for any sign of a break in their iron uniformity.
On February 16th, 1801, Matthew Flinders was promoted to the rank of commandant, and left England with the INVESTIGATOR, to prosecute his voyage to Terra Australis. His instructions were:—
"To make the best of your way to New Holland, running down the coast from 130 degrees east longitude to BASS'S Straits, putting, if you should find it necessary, into KING GEORGE THE THIRD'S HARBOUR for refreshments and water, previous to your commencing the survey, and on your arrival on the coast, use your best endeavour to discover such harbours as may be in those parts, and in case you shall discover any creek or opening likely to lead to an INLAND SEA OR STRAIT, you are at liberty either to examine it or not, as you 'shall judge it most expedient, until a more favourable opportunity shall enable you so to do.
"When it shall appear to you necessary, you shall repair to SYDNEY COVE, for the purpose of refreshing your people, refitting the sloop under your command, and consulting the Governor of New South Wales upon the best means of carrying on the survey of the coast; and having received from him such information as he may be able to communicate, and taken under your command the LADY NELSON tender, which you may expect to find in Sydney Cove, you are to recommence your survey by first diligently examining the coast from BASS'S Straits to KING GEORGE THE THIRD'S HARBOUR."
Flinders was then instructed to repair from time to time to Sydney Cove, to be very diligent in the examination, and to take particular care to insert in his journal every circumstance that might be useful to a full and complete knowledge of the coast—the wind, weather, the productions, comparative fertility of the soil, the manners and customs of the inhabitants, and to examine the country as far inland as it was prudent to venture with so small a party as could be spared from the vessel whenever a chance of discovering anything useful to the commerce or manufacturies of the United Kingdom.
From thence they were to explore the north-west coast of New Holland, where, from the extreme height of tides observed by Dampier, it was thought probable valuable harbours might be found; also the Gulf of Carpentaria and the parts to the westward. When that was completed, a careful investigation and accurate survey of Torres Straits; then an examination of the whole of the remainder of the north, the west, and the north-west coasts of New Holland.
"So soon as you shall have completed the whole of these surveys and examinations as above directed, you are to proceed to, and examine very carefully the east coast of New Holland, seen by Captain Cook, from Cape Flattery to the Bay of Inlets; and in order to refresh your people, and give the advantages of variety to the painters, you are at liberty to touch at the Fijis, or some other islands in the South Seas."
As soon as the whole of the examinations and surveys were completed, he was to lose no time in returning with the sloop under his command to England.
The vessel was fitted with a plant cabin for the purpose of making botanical collections for the Royal Gardens at Kew, and on each return to Sydney Cove, all plants, trees, shrubs, etc., were to be transferred to the Governor's garden until the INVESTIGATOR sailed for Europe.
